Kathleen Folbigg pardoned after 20 years in prison for child murder.

Kathleen Folbigg, an Australian woman who spent 20 years in prison for killing her four children, has been pardoned and released based on new scientific evidence that the children died of natural causes. The pardon was granted by the Governor of New South Wales following a second inquiry into her guilt, which found reasonable doubt based on the new evidence. Folbigg had been serving a 30-year prison sentence, which was set to expire in 2033.
